Interaction design schools

Hello everybody,
I’m a 22 year-old boy from Italy, I got a first level degree in Industrial Design at Polytechnic university of Turin in December. My thesis was about interaction design and tangible user interfaces (you can take a look at the project here Tangible user interface for music learning on Vimeo ), and I’m willing to get a second level degree with a focus on interaction design. Can you suggest me some good schools around the world and your experience with them? I was thinking about Sweden, I saw that there are a couple of universities there with interaction design courses, do any of you went there?
Please consider that I cannot afford to pay more than 2000$/year for the fees :unamused:

Thank you in advance for the feedback!
